FABRIC AND PROCESS OF TREATING THE SAME.

No Drawing.

T 0 all whom it may concern:

Be it known that I, NATHAN HIRSCH, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Fabrics and Processes of Treating the Same, of which the following is a full, clear, and exact disclosure.

The present invention relates to that class of fabrics designed for use as a flexible duck or canvas for Wearing apparel.

The object of my invention is to produce a fabric for the purpose stated, which may be made of cotton, but which will not shrink In carrying out my invention,

or change its shape when moistened, and one which will notbecome stlfi' and inflexible when pressed or ironed with a hot iron.

Heretofore in the making of wearing apparel, linen duck has been largely used as a material for lining and giving bod to parts of the apparel. Linen is particu arly adapted for this use inasmuch as it is less liable to shrink than cotton and will not be- 'come as stiff and unpliable when pressed with a hot iron after being moistened.

Linen thus used is expensive and it is therefore one object of my invention to produce a fabric which may be used in the place of linen, but which will have all of the desirable qualities possessed by the more expensive material.

I employ a textile fabric of suitable weave, preferably of cotton. The fabrics to Which my invention is particularly applicable, are those known as paddings or elastic ducks used in the making up 9f custom made garments and other Wearing apparel. This fabric is first bleached in the usual or well known way after which it is subjected to the action of a material having a shrinking or contrac- Specification of Letters Patent.

plied, the fabric is dried, and preferably at the same time subjected to the action of a tentcring machine. The action of thetentering machine prevents the fabric from drying as a stiff unpliable body and renders the fabric of practically the same texture as linen heretofore used in the padding or lining of garments.

The tentering action is a manipulation or working of the fabric so that the" warp is prevented from adhering to the woof thereof, thereby retaining the flexibility of the This tenterin is tobe distinguished from stretching, whic has heretofore been resorted to in the preparation of ordinarycotton lining or material for garments. As an e. :ampleof the action of the process of my invention, it may be said that a piece of cotton lining material which originally is thirty-six inches in width, will be contracted b the action of the caustic alkali to a widt of twenty-seven or twenty-eightinches which width is practically that ofthe finished material since the tentering action simply loosens and prevents adhesion between the threads.

By treating a cotton fabric in the manner above set forth, a fabric will be produced which will not become stiff after moistening and ironing or pressing and one which is fixed in its dimensions, that is, will not shrink or enlarge under the action of moisture and which at the same time retains its original elasticity and pliability under the usual conditions of use to which such fabrics are submitted.

The fact that cotton may be used as original fabric in which these qualities are embodied. enables me to produce a fabric that is much less expensive to manufacture and therefore can be used in a class of garments, the selling price of which will preclude the use of linen as a paddin or lining material.

Having thus described my invention, what I claim and desireto protect by Letters Patcut is:

1. The process of producing a cotton liningor stiffening fabric which comprises, submitting a cotton fabric of substantially the Weave and weight of the usual linen stiffening material to the action of caustic alkali having a shrinking or r'ontractive action, thereafter sizing the same, then drying and at the same time submitting the fabric in its shrunken condition to a mechanical' action which prevents adhesion between the" threads and renders the fabric pliable Without being stretched.

2. An article of manufacture, a cotton lining and stiffening fabric consisting of a sized I cotton fabric of substantially the weave and weight of the usual linen stifi'ening material, chemically shrunk and having a permanent set in dimensions less than that produced by moisturerthe threads of the 10 EDWARD W.
